Ok guys, the fj40 project is getting close, trying to get it on the road before #2 arrives in july. here's the mess i'm in right now:

I have a '67 gas tank, a 2F with a '78 mechanical pump, and a unknown year fj60 carb. what i noticed is that the fj60 carb has no fuel return port, that is handled by the fuel pump for those years. so my first thought was to get an fj60 pump as well, but the fj60 pump wants to pump the excess fuel back to the tank, and the '67 tank has no fuel return port. anyone ever put a 60 carb on a 40 and how did they address this if at all?

alright, forget it, i'm going to keep it simple and go with a 40 carb. i think i have enough pieces around to make one usable frankencarb.

Kipper,

No help on your question but I have a couple carbs in my garage if you come up short on parts...Not sure if either would work for you. My plan was to revert the 40 back to an Aisin carb from the Weber, someday - I only really need 1 good/complete carb out of the two I have

Kipper, I'm pretty sure that your 60 carb return fuel line issue has been solved before. You might do a Mud search. Or you might post on the LCML. You might also send a PM to Jeff Zepp -- if he doesn't know the answer, he'll know who to ask. He's not on the RS forum as frequently as in the past -- TLCA business has him busy, and there's only so many hours in the day, y'know.

Early rigs had no fuel return whatsoever. Middle years returned it to the tank (which won't work with the '67 tank. Later years (FJ60s for example) returned the fuel to the pump, which had an extra upstream fitting for that purpose.

Which 40 carb are you thinking of using? Various years (assuming 2bbl) had various attributes which are considered desirable. What distributor are you planning on using? Jim Chenoweth is a fan of frankencarbs, but which carb parts you plan on using is decided in part by what distributor and what (if any) emissions systems are planned.
